Tokyo, Japan - Researchers from Tokyo Metropolitan University have developed a way to mount gold nanoparticles on a molecular support known as a polyoxometalate (POM). They successfully applied this to realize nearly 100% conversion of carbon monoxide (CO) over a wide temperature range, demonstrating stable performance over long periods of time. They showed how traces of water uniquely contribute to the catalyst's function, promising insight into catalysis and potential application to exhaust gas and room air purification.

Two Waterloo chemists have made it easier for manufacturers to produce a new class of faster and cheaper semiconductors.

The chemists have found a way to simultaneously control the orientation and select the size of single-walled carbon nanotubes deposited on a surface. That means the developers of semiconductors can use carbon as opposed to silicon, which will reduce the size and increase the speed of the devices while improving their battery life.

Thousands of animals including elephants, tigers, rhinos, and gorillas are poached each year. Researchers at the USC Center for Artificial Intelligence in Society have long been applying AI to protect wildlife. Initially, computer scientists were using AI and game theory to anticipate the poachers' haunts, and now they have applied artificial intelligence and deep learning to spot poachers in near real-time.

COLLEGE PARK, Md. - The ability for cancer cells to develop resistance to chemotherapy drugs - known as multi-drug resistance - remains a leading cause for tumor recurrence and cancer metastasis, but recent findings offer hope that oncologists could one day direct cancer cells to "turn off" their resistance capabilities.

PROVIDENCE, R.I. [Brown University] -- Researchers from Brown University and MIT have developed a method for helping robots plan for multi-step tasks by constructing abstract representations of the world around them. Their study, published in the Journal of Artificial Intelligence Research, is a step toward building robots that can think and act more like people.

Biomedical engineers have developed a miniature self-sealing model system for studying bleeding and the clotting of wounds. The researchers envision the device as a drug discovery platform and potential diagnostic tool.

A description of the system, and representative movies, were published Tuesday online by Nature Communications.

Lead author Wilbur Lam, MD, PhD says that blood clotting involves the damaged blood vessel, platelets, blood clotting proteins that form a net-like mesh, and the flow of the blood itself.

The American College of Rheumatology (ACR) has published a new white paper, "The Science Behind Biosimilars - Entering a New Era of Biologic Therapy," providing a comprehensive overview of the scientific, clinical, economic and prescribing issues pertaining to biosimilar use, including efficacy, competition and drug pricing.

The vapour from e-cigarettes seems to help pneumonia-causing bacteria stick to the cells that line the airways, according to research published in the European Respiratory Journal [1].

The study included experiments with cells, mice and humans. It showed that e-cigarette vapour had an effect similar to the reported effects of traditional cigarette smoke or particulate matter from fossil-fuel pollution, both of which are known to increase susceptibility to lung infection with pneumococcal bacteria.

COLLEGE PARK -- Engineers at the University of Maryland, College Park (UMD) have found a way to make wood more than 10 times stronger and tougher than before, creating a natural substance that is stronger than many titanium alloys.

Bethesda, MD - Feb. 7, 2018 - Stephen Curry, Professor of Structural Biology at Imperial College in London, is calling for research assessment reform to become more than just words. As chair of a new steering committee behind the San Francisco Declaration on Research Assessment (DORA), Professor Curry's call to action is bolstered by investments from nine organizations in the U.S. and Europe combined with signatures on the Declaration for each of the U.K.'s seven Research Councils.
